S&W are now shipping the M&P 22 with already threaded barrels they raised the price on it , but what do you expect.
Price? How much was the threading? I just got a 10/22 in ACU and it needs a threaded barrel.
Just shot today mine for the first time. Put about a hundred rounds of blazer and cci mini mags through it without the first problem. It's a great little shooter.
